  4. 2. Micro-cracking and delaminations of composite laminates under tensile quasi-static and cyclic loading

    Author : Hiba Ben Kahla; Janis Varna; Zoubir Ayadi; Federica Daghla; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Laminate; Fatigue; damage growth; stiffness reduction; NCF; Polymeric Composite Materials; Polymera kompositmaterial;

    Abstract : Aerospace industry is devoted to improving the aircraft performance while reducing its weight and limiting the emissions. Part of this objective can be accomplished with the use of high-performance long fibre reinforced polymer laminated composites. READ MORE

  5. 3. Simulation of Delamination Initiation and Growth in Fiber Composite Laminates

    Author : Rikard Borg; Michael R. Wisnom; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis concerns the topic of delaminations in unidirectional fiber reinforced plastic composite laminates.A model for the simulation of delamination initiation and growth has been developed. It is based on fracture mechanics and formulated as a combination of a cohesive zone model and a linear elastic adhesive penalty formulation. READ MORE

  6. 4. Resin transfer moulded composite materials : processing, structure, property relationships

    Author : J. Anders Holmberg; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymera konstruktionsmaterial; Polymeric Composite Materials;

    Abstract : This thesis contains analysis of the performance of polymer composites manufactured by resin transfer moulding (RTM). The thesis consists of six papers, where the first two deals with the tensile strength of composites reinforced with randomly oriented glass fibres, which still is the most common reinforcement in RTM manufacturing.
